theoretically SMF format 1 does support polyrythmic
sequences as each
MTrk might have each its own arbitrary tempo and time-sig meta-event
sequences.
Theorectically yes, but such a file would not be compliant to the
standard, as it specifically says:
"for a format 1 file, the tempo map [ie. tempo meta events] must be
stored as the first track."
and:
"In format 1, these meta-events [ie.e tempo and time signature] should
be contained in the first track."
If you want several tracks with different tempi, use a format 2 file,
but then the tracks are not assumed to be related to each other at all.
In other words, it's like multiple format 0 file tracks in one file.
